Abstract

The invention relates to a hydraulically actuable releaser with an annular piston. The supporting ring co-operating with the annular piston and the groove sealing ring co-operating with the supporting ring have, at least in their radially outer region facing one another, an encircling supporting shoulder on the supporting ring and an encircling recess on the groove sealing ring. This measure prevents the groove sealing ring from being pressed into a possible gap between supporting ring and the external wall of the housing under pressure loading.
